40 more |
Before |
10 u |
5x2 + 40 =
10 u + 40 |
Change |
- 7 u |
- 2x2 - 16 =
- 4 u - 16
|
After |
3 u |
3x2 + 24 =
6 u + 24 |

and wafers in the end |

45 more |
0.7 =
710 25 x 40 = 16
Number of wafers that Aunt Jean gave to Gillian = 4 u + 16
If Aunt Jean made another 45 macarons in the end, the number of macarons and wafers in the end would be the same.
6 u + 24 = 3 u + 45
6 u - 3 u = 45 - 24
3 u = 21
1 u = 21 ÷ 3 = 7
Number of macarons that Aunt Jean made
= 10 u
= 10 x 7
= 70
Answer(s): 70
